D-Band (130-175 GHz)
Sub-Terahertz Extreme High-Capacity Frequency Window
Sub-THz spectrum band providing tens of gigahertz of contiguous bandwidth for ultra-high-speed wireless backhaul, kiosks, and indoor hotspots.
Technical Explanation
The D-Band (130 to 175 GHz) represents the premier testing ground for sub-terahertz 6G communications. Offering wide atmospheric attenuation transmission windows between water vapor absorption dips, the D-band accommodates contiguous spectrum channels up to 10 GHz wide. When deployed on high-capacity point-to-point links or high-density indoor venues, it delivers wireless throughput exceeding 100 Gbps, matching optical fiber performance.
Key Functions
- Accommodates ultra-wide contiguous frequency channels up to 10 GHz wide
- Provides wireless backhaul and front-haul replacement for high-cost optical fiber
- Enables terabit data transfer kiosks and indoor holographic conferencing
- Exhibits lower atmospheric absorption compared to higher 200+ GHz windows
